QCX/OnStream

QCX/OnStream combines high frequency sampling and energy dispersive X-ray fluorescence analysis (EDXRF) techniques to provide tight on-line chemical quality control of cement raw mix or other powder process streams. Elements from Mg and upwards in the periodic system can be analyzed with adequate analytical performance. Thus, in a cement application all the 4 key elements (Al, Si, Ca, Fe) can be analyzed for. Analysis of Mg and/or S are available options .

Application

The basic operation principle is that a sampler extracts a small bypass sample stream from the powder process stream. Every approx 6-7 minutes a sample dosing device extracs a small sample portion from this bypass sample stream. The sample portion is delivered to a cavity in a revolving circular tray. After dosing, next step is low pressure pressing followed by sample presentation to the analyzer head, mounted in a fixed position over the revolving tray. The sample is analyzed for typically 2-3 minutes, whereafter the last step in the handling cycle is reject of the sample portion or collection of same into an optional composite sample mixing container .
